WebIf you're asking for the area of the sector, it's the central angle of 360, times the area of the circle, for example, if the central angle is 60, and the two radiuses forming it are 20 inches, you would divide 60 by 360 to get 1/6. And solve for area normally (r^2*pi) so you would get 400*pi, than divide by 6, you would get around 209.
